The healthcare provider is planning care for a client at 30 weeks gestation who is experiencing preterm labor. Which medication is most important in preventing this fetus from developing respiratory distress syndrome?
- A. Ampicillin 1 gram IV push every 8 hours
- B. Betamethasone 12 mg deep IM
- C. Terbutaline 0.25 mg subcutaneously every 15 minutes for 3 doses
- D. Butorphanol tartrate 1 mg IV push every 2 hours as needed
Correct Answer: B
Rationale: Betamethasone is a corticosteroid given to stimulate fetal lung maturity and reduce the risk of respiratory distress syndrome in preterm infants. Ampicillin (Choice A) is an antibiotic and does not prevent respiratory distress syndrome. Terbutaline (Choice C) is a tocolytic used to inhibit contractions and does not directly prevent respiratory distress syndrome. Butorphanol tartrate (Choice D) is an opioid analgesic and does not have a role in preventing respiratory distress syndrome in preterm infants.

Humans begin life as a single cell that divides repeatedly. This cell is known as a(n):
- A. zygote.
- B. gonadotrope.
- C. embryo.
- D. chromaffin.
Correct Answer: A
Rationale: A zygote is the correct answer. It is the initial cell formed when a sperm cell fertilizes an egg cell, marking the beginning of human development. Choice B, gonadotrope, is incorrect as it refers to a type of hormone-secreting cell in the pituitary gland. Choice C, embryo, is incorrect as it is the stage of development after the zygote has implanted into the uterine wall and undergone initial cell divisions. Choice D, chromaffin, is incorrect as it refers to cells found in the adrenal medulla that produce and store catecholamines.
A newborn who was born post-term is being assessed by a nurse. Which of the following findings should the nurse expect?
- A. A Rh-negative mother who has an Rh-positive infant
- B. A Rh-positive mother who has an Rh-negative infant
- C. A Rh-positive mother who has an Rh-positive infant
- D. A Rh-negative mother who has an Rh-negative infant
Correct Answer: A
Rationale: The correct answer is A: 'A Rh-negative mother who has an Rh-positive infant.' In cases where the newborn is born post-term, the mismatched Rh factor between the mother (Rh-negative) and the infant (Rh-positive) can lead to hemolytic disease of the newborn. This condition occurs when maternal antibodies attack fetal red blood cells, causing hemolysis. This can result in jaundice, anemia, and other serious complications for the infant. Choices B, C, and D are incorrect because they do not reflect the mismatched Rh factor scenario that poses a risk for hemolytic disease of the newborn.
A client who has mild preeclampsia and will be caring for herself at home during the last 2 months of pregnancy is receiving teaching from a healthcare provider. Which statement by the client indicates an understanding of the teaching?
- A. "I will count baby's kicks every other day."
- B. "I will alternate the arm used to check my blood pressure."
- C. "I will consume 50 grams of protein daily."
- D. ---
Correct Answer: B
Rationale: The correct answer is B. Alternating arms for blood pressure checks ensures more accurate readings and helps monitor preeclampsia. Option A, counting baby's kicks every other day, is not specific to managing preeclampsia. Option C, consuming 50 grams of protein daily, is important for a healthy diet during pregnancy but does not directly relate to preeclampsia management.
A client is receiving an epidural block with an opioid analgesic. The nurse should monitor for which of the following findings as an adverse effect of the medication?
- A. Hypotension
- B. Polyuria
- C. Bilateral crackles
- D. Hyperglycemia
Correct Answer: C
Rationale: The correct answer is C: Bilateral crackles. Bilateral crackles indicate respiratory complications, which can occur as an adverse effect of an epidural block with opioid analgesics. Hypotension (Choice A) is a common side effect of epidural opioids but is not typically monitored via crackles. Polyuria (Choice B) is excessive urination and is not directly associated with epidural blocks. Hyperglycemia (Choice D) is high blood sugar levels and is not a typical adverse effect of epidural opioids.
A client who delivered a healthy newborn an hour ago asked the nurse when she can go home. Which information is most important for the nurse to provide the client?
- A. After the baby no longer demonstrates acrocyanosis
- B. After the baby receives the vitamin K injection
- C. When ambulating to avoid causing dizziness
- D. When there is no significant vaginal bleeding
Correct Answer: D
Rationale: The most critical information for the nurse to provide the client is ensuring that there is no significant vaginal bleeding before discharge. This is vital to prevent complications such as postpartum hemorrhage. Options A, B, and C are important aspects of postpartum care, but assessing and managing vaginal bleeding takes precedence due to its potential seriousness.
